iPhone: You have plenty of choices for to-do lists on the iPhone, but Begin is an app that hits that spot between simplicity and usability. Begin's fast, gesture driven, and gives you just two categories for your list: today and tomorrow.

Begin's main purpose is simplicity. It launches incredibly fast, and it's easy to add tasks to your list so you can get on with your day. Everything you add is immediately added to "today" and you can shift it over to tomorrow if you can't get to it. Every day, Begin clears out your old list so you can start again. Begin's strength is simplicity, so don't expect push notifications, multiple lists, or cloud syncing. It's about getting in, doing your tasks, and getting out quickly.
